Those are the main ones I'd like to make common to all. I was also wondering about /var (or at least /var/log). Would that be OK to share amongst the distros? I'm thinking /var may cause problems with package management? Any other possibilities?

I haven't bothered with virtualization before because the vista on my dual boot PC has no external disk, only the recovery partition. I wouldn't think it's possible to set up vista as a virtual machine that way and I don't want it to be my main OS with linux as the virtual OS. I may have to leave vista as a reboot option. But I suppose another big reason I haven't ventured into virtualization is that I don't know how to do it and it takes no brains to reboot to different OS's.  

No a vista recovery disk isn't going to work.  Not sure the license
on the OEM version even permits using it with a virtual machine.
Retail versions certainly do for some variants.

The way I do things is:

kvm-img create debian-kfreebsd.img 20G
kvm -usbdevice tablet -daemonize -smp 2 -m 512 -hda debian-kfreebsd.img -vga std -cdrom debian-20090729-kfreebsd-amd64-install.iso -boot d

Then after installing I use

kvm -usbdevice tablet -daemonize -smp 2 -m 512 -hda debian-kfreebsd.img -vga std
